I need to install a new concrete ring beam. Tight space and complex job, mainly due to snotty neighbour restricting access and not wanting scaffold on his crappy piece of scrap strewn, weed infested, dog shit covered "lawn".
I seem to recall seeing in France a small metal bar, slightly bent, a bit like a metal door handle that is secured to a wall below the wooden form and then when tapped in it will hold the form in place while under it's own pressure. Similar to a shutter latch.
I've tried Google, but as I don't know what they are called I have not a clue what I should be looking for.
Anyone got any ideas?
